Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Wings (github.com/pterodactyl/wings) versions before 1.13.0 are affected. The config file parsers for json, yaml, xml and similar formats do not limit file size, so a very large config file can exhaust memory and crash the wings process. The source describes the trigger as a maliciously or erroneously created config file, and it applies to eggs that use a non-file parser configuration setting. Upgrade to version 1.13.0 or later.
